To all whom it may concern.-

Be it known that I. THOMAS STANLEY, a .citizen of the United States,residing at Pueblo, in the county of Pueblo and State of Colorado, haveinvented certain new and useful Improvements in Drilling-Machines, ofwhich the following is a full, clear,and exact description.

This invention is an improvement in drilling-machines intendedespecially for use in drilling wells, but which may also be used fordigging post or other holes; and the invention consists in certainfeatures of construction and novel combinations of parts, as will behereinafter described, and pointed out in the claims.

In the drawings, Figures 1 and 2 are side elevations of my improveddrilling-machine. Fig. 3 is a horizontal section of the machine, andFigs. 4 and 5 are detail views.

The derrick or support A is formed with the outer base-bars 1, inner orcross base-bars 2, uprights 3,top frame 4, cross-bars 5, connecting theuprights 3 about midway the height of said uprights, and theintermediate upright 6, extended between the top frame and one of thecross-bars 5.

The shaft B is jonrnaled in suitable bearing-frames C, and is providedat one end with a pulley 7 and at its opposite end with a crank 8. Thiscrank 8 may serve as a hand-crank by which to turn the shaft 13, or thesaid shaft may be driven by an engine by means of a belt applied to thepulley 7. When the shaft is driven by an engine, as described, the crank8 may be connected with a bellows for use with the fire employed inshaping the drilling-tools, if desired, or for other purposes, as may bedesirable or necessary. The shaft 13 also has a wiper-cam 9 and a pulley10 for use in the manner hereinafter described. 011 the crossbars 5 Ipivot levers D, preferably four in number and arranged to convergetoward their inner ends, the outer ends or arms of the said leversprojecting outward from the bars 5, as shown. Cords 11 connect with theouter ends of the levers D, extend thence down under guide-pulleys 12,thence under guide-pu1leys 13, arranged close together in a block E, andthence up and connect with the inner end of a lever E, which is pivotedto the derrick-frame and has its outer end arranged to be engaged anddepressed by the cam 9 as the shaft B is turned. This depressing of theouter end of the lever F operates through the connections described toelevate the inner ends of levers D. The said inner ends of the levers Dare connected by means of links 14: with a connecting-hanger G, havingat its upper end a flange l5, with which the links 14 connect, so thatthe movements of the levers D operate to reciprocate theconnecting-hanger G vertically. At its lower end the hanger G has a ringor opening 15, through which the drill-rope H is looped and held by apin I, so that the upward movement of the connection G will lift thedrill-rope and the attached drilling devices or tools, which will dropof their gravity when released.

It is preferred to provide Weights 16 on the inner ends of arms D, sothat the levers D will drop at their inner ends Without. impeding thedropping of the drill-tools. The drillrope H extends up over a pulley 17and thence down and connects with the drill-rope reel J.

The sand-pump K has its rope L carried up over a pulley 18 and thencedown and secured to the sand-reel M, which is arranged by preferenceabove the drill-rope reel.

1 sleeve or journal the reel J on the shaft N of the drive-gear wheel 0,which wheel is fixed to its shaft and is formed with a gearring 19, aband-pulley 20, and a pulley-bearing 21 for the strap-brake 22, whichmay be operated by means of the lever 23 and cord 24. The drive-gear isdriven by the belt-cord 25 from the pulley 10 of shaft B. The drillropereel is movable longitudinally on the shaft of the drive-gear and has aclutch-section 26, which is set into and out of engagement with theclutch-section 27, fixed to such shaft, so that the drill-rope reel maybe set into connection with or freed from the operating drive-gearwheel. The sand-reel shaft is also movable longitudinally and has apinion 28, which is movable into and out of gear with the gearring 19 ofthe drive gear wheel 0.

To enable the movement of one or the other of the reels into connectionwith the drivegear wheel, I provide the lover I pivoted bettweenits endsand connected at its opposite end to the sand-reel and drill-rope reel,so that as one is moved into connection with the drivc-gear the otherwill be moved out of such connection.

Cords 29 and 30 connect with the opposite ends of the lever P and extendover guidepulleys and into convenient reach from the ground, enablingthe operator standing on the ground to adjust either reel intoconnection with the drive-gear wheel.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In an apparatus substantially as described, the combination, with thedrill de- Vices, the operating mechanism, and the pinrality of leversarranged approximately opposite each other and to converge toward theirinner ends, of connections between the inner ends of said levers and thedrilling devices, the ropes extended from the outer ends of the saidlevers and the operating; mechanism, and independent guides for the saidropes, whereby they are all properly directed to a common operatingmechanism, all substantially as and for the purposes set forth.

2. In an apparatus substantially as described, the combination of theframing, the operating mechanism, the drill-rope, the levers arranged toconverge toward their inner ends, the connectingllanger G, supported onthe inner ends of said levers and provided with a ring or openingthrough which the drill-rope is loopedand held,the drill devicesconnected with the said rope below such hanger, and the ropes connectingthe outer ends of the said levers with the operating mechanism, allsubstantially as and for the purposes set forth.

3. In an apparatus substantially as described, the combination of thederrick or support, the drill device, the series of levers havingtheirinner ends arranged to converge and connected at such inner endswith the drill devices, the lever F, the ropes extended between saidlever and the outer ends of the converging levers, and guides for saidropes, all substantially as and for the purposes set forth. i.

4. In an apparatus substantially as described, the combination of thedrive-gear wheel, the sandpump reel having its shaft provided with apinion movable into and out of mesh with the said gear-Wheel, thedrillrope reel, the clutch mechanism by which the drill-rope reel may bekeyed to the drive-gear wheel, and a connection between said pinion andclutch mechanism whereby the movement of one will positively effect themovement of the other, all substantially as set forth.

5. The combination, in an apparatus sub stantially as described, of thedriy'egear wheel, the sand-reel havingits shaft provided with a pinionmovable into and out of mesh with the drive-gear wheel, the drive-ropereel, the clutch having a section fixed with respect to the drive-gearwheel and its other section fixed to the drill-rope reel, and the leverpivoted between its ends and connected at one end with the sand-reelshaft and at its other end with the drill-rope reel, all arranged tooperate substantially as described, and for the purposes set forth.

6. In an apparatus substantially as described, the combination of thederrick or support, the drill-rope, the reel and guides for suchdrill-rope, the plurality of approximately oppositely-arranged leversconverging toward their inner ends, a connection-piece suspended on theinner ends of said levers, and devices for securing the drill-rope tothe said connection-piece, the drill-rope being extended beyond suchconnection-piece and supporting the drill devices, all substantially asand for the purposes set forth.
